Definitions

  • This invention relates to a side door hinge mechanism in a motor vehicle, in which a quadric crank chain mechanism is utilized.
  • the side door in a motor vehicle e.g. passenger car has heretofore been installed in a manner to be rotatable about a hinge affixed to a vehicle body for opening or closing.
  • a door opening angle corresponding to the total length of the side door is required.
  • one of the aforesaid front rotary link is formed by interconnecting two points including the front end point of the side door, possibly the foremost point, and a point forwardly of the front pillar, so that the side door is slidable forwardly to a considerable extent.
  • the primary object of the present invention is to provide a side door hinge mechanism in a motor vehicle, capable of allowing an occupant of a vehicle to easily get on or off the vehicle by opening a side door even when a space at the side of the vehicle is small.
  • the present invention has as its secondary object the provision of a quadric crank chain type side door hinge mechanism capable of allowing the occupant to further easily get on or off the vehicle in a side door opened state.
  • the present invention has as its object the provision of a side door hinge mechanism in a motor vehicle, utilizing a quadric crank chain, in which the front rotary link is formed by interconnecting two points including the front end point of the side door and a point forwardly of the front pillar, without curving the rotary link, designing the side door into an unusual shape or increasing the weight and the area of the side door.
  • a quadric crank chain comprises: a front rotary link interconnecting two points which are disposed at the front side of a vehicle body and a side door as rotary shafts out of four points including two points disposed on the vehicle body and spaced apart from each other in the longitudinal direction of the vehicle body and two points disposed on the side door and spaced apart from each other in the longitudinal direction of the side door, a rear rotary link interconnecting two points disposed at the rear sides as rotary shafts, a portion between the two points on the vehicle body, and a portion between the two points on the side door; the rotary shaft at the front side of the vehicle body is disposed forwardly of the rear end of a front fender and inwardly of the front fender, a portion of the front fender, which covers the outer surface of the aforesaid front rotary link, is divided from a main body of the front fender to be formed into a
  • the present invention contemplates that the rotary shaft of the aforesaid front rotary link on the side door is disposed at a position close to the forward end portion of the side door, whereby the front rotary link is disposed at a position where it does not hinder the occupant from getting on or off the vehicle.
  • the present invention contemplates that said rotary shaft of the front rotary link on the side door is disposed on an end panel at the forward end portion of said side door.
  • the present invention contemplates that the rotary shaft of the rear rotary link on the vehicle body is disposed at a position close to the rear end of a front pillar, whereby the rear rotary link is disposed at a forward position where it does not hinder the occupant from getting on or off the vehicle.
  • said movable fender comprises a portion of said front fender, said portion being disposed rearwardly of a front wheel and generally being lower than at least said front rotary link.
  • said front rotary link is disposed at the lower portion of said side door and rearwardly of a front wheel.
  • a quadric crank chain comprises: a front rotary link 4 interconnecting two points which are disposed at the forward sides of a vehicle body 2 and a side door 3 in a motor vehicle 1 as rotary shafts 2A and 3A out of four points including two points disposed on the vehicle body 2 and spaced apart from each other in the longitudinal direction of the vheicle body.2 and two points disposed on the side door 3 and spaced apart from each other in the longitudinal direction of the side door 3; a rear rotary link 5 interconnecting two points disposed at the rear sides as rotary shafts 2B and 3B; a portion between the two points on the vehicle body 2; and a portion between the two points on the side door 3, whereby a side door hinge mechanism in a motor vheicle is formed.
  • the respective rotary shafts 2A, 2B, 3A and 3B are elongated in the vertical direction of the vehicle body, and the front rotary link 4 and the rear rotary link 5 and formed to have large widths in the vertical dirction, corresponding to the lengths of these rotary shafts, respectively.
  • the front rotary link 4 and the rear rotary link 5 control a moving path of the side door 3 during its opening or closing, and support the weight of the side door 3 as well.
  • the front rotary shaft 2A on the vehicle body 2 is disposed forwardly of the rear end of a front fender 6 and inwardly of the front fender 6, and a portion of the front fender 6, which covers the outer surface of the front rotary link 4, is divided from a main body of the front fender 6 to be formed into a movable fender 6A rotatable with the front rotary link 4.
  • this movable fender 6A as centered about the rotary shaft 6A is provided rearwardly of a moving path of a front wheel 7 as shown in Fig. 3, whereby, the movable fender 6A does not interfere with the front wheel 7.
  • the rotary shaft 3A of the front rotary link 4 on the side door 3 is disposed at a position close to the forward end portion of the side door 3, e.g. on a front end panel 9, and the rotary shaft 2B of the rear rotary link 5 on the vehicle body 2 is disposed at a position close to the rear end of a front pillar 8.
  • the rotary shaft 3B of the rear rotary link 5 on the side door 3 is disposed at a position inwardly of the substantially central portion in the longitudinal direction of the side door 3.
  • the front rotary link 4 is made to be shorter in length than the rear rotry link 5, so that the rear portion of the side door 3 can be opened wider than the forward portion thereof in a fully opened state of the side door 3 as indicated by two-dot chain lines in Fig. 3.
  • Reference numeral 5A designates a cover of the rotary link 5.
  • the side door 3 is opened or closed by the quadric crank chain mechanism, so that, even when a space at the side of the motor vehicle 1 is small, an opening for allowing the occupant to get on or off the vehicle can be obtained without making the side door 3 to greatly project sidewards.
  • a portion of the front fender 6 is formed into the movable fender 6A and this movable fender 6A is made rotatable with the front rotary link 4, whereby the front rotary link 4 and the rotary shaft 2A thereof can be disposed frowardly, so that, when the side door-3 is opened, a forwardly movement value of the side door 3 can be increased to provide a sufficient opening for allowing the occupant to get on or off the vehicle.
  • the two rotary links 4 and 5 when the side door 3 is opened or closed by the quadric crank chain mechanism as described above, the two rotary links 4 and 5 must support not only the weight of the side door 3 but also the side door 3 against an angular moment of the side door 3 in the direction of thickness thereof. For this purpose, it is desirable that the two rotary links 4 and 5 be offset in the vertical direction.
  • the front rotary link 4 and the rear rotary link 5 are offset in the vertical direction, it is desirable that at least a portion of the front rotary link 4 be positioned forwardly of the front pillar 8. In order to prevent the front rotarty link 4 from interfering with the front fender 6 at this time, it is necessary to mount the front rotary link 4 onto the undersurface of a floor of the motor vehicle 1.
  • the front rotary link 4 supports the weight of the side door 3 in cooperation with the rear rotary link 5, whereby the front rotary link 4 is increased in width in the vertical direction.
  • the front rotary link 4 is mounted onto the undersurface of the floor of the motor vehicle 1, such a disadvantage is presented that a projection value of the front rotary link 4 projecting downwardly is considerably increased.
  • a portion of the front fender 6 is formed into the movable fender 6A and the front rotary link 4 is disposed inwardly of the movable fender 6A, so that the aforesaid disadvantage can be obviated.
  • the rotary shaft 2B of the front rotary link 4 on the side door 3 is disposed at a position close to the forward end portion of the side door 3, so that the front rotary link 4 can be desirably set in its mounted position in the vertical direction with the front rotary link 4 not interfering with the front pillar 8.
  • the rotary shaft 2B of the rear rotary link 5 on the vehicle body 2 is disposed at a position close to the rear end of the front pillar 8, so that, when the side door 3 is opened, the rear rotary link 5 can stay at a position least hindering the occupant from getting on or off the vehicle.
  • the weight of the side door 3 is supported by the front rotary link 4 and the rear rotary link 5.
  • the two rotary links 4 and 5 merely control the moving path of the side door 3, and consequently, the weight of the side door 3 may be supported by a member other than these rotary links 4 and 5.
